Canis armbrusteri

Canis armbrusteri or Armbruster's Wolf is an extinct species of wolf that lived in North America from 1.8 million
to 300 thousand years ago. It is thought to have possibly evolved from the Canis chiliensis in Asia. Fossils of
the Canis armbrusteri have been found throughout the United States. Fossil remains were first found at Cumberland
Cave in Maryland. The oldest fossils have been found in the southwestern United States, and later fossils have
been found scattered across the country. One speciman of the wolf was estimated to weigh 139 pounds and another
specimen was estimated to weigh 119 pounds (reasonably larger than the grey wolf
of today). The Canis armbrusteri was classified in 1913 by Dr. James W. Gidley.
